A solutionof anorganiccompoundis preaped by dissolving68.4 g in 1000 g ofwater .Calculatepressureof thesolutionat 293 K when elevationin boiling point is 0.104 andK_(b)for wateris 0.53 Km^(-1) .

Answer»


Solution :`M_(B)= (0.52 xx 68.4 xx 1000)/(0.104 xx 500) = 342`
` pi= (68.4 xx 0.082 xx 293)/(342 xx 500) = (V = 1000 g=1 L)`
` = 4.80` atm.
